Arizona Building Codes and Contacts

The following information is reprinted with permission from the Building Codes Assistance Project:

Current Commercial Code

No statewide code. The majority of localities have adopted, at minimum, the 2009 IECC.

Many populated areas of Arizona have adopted some version of the IECC. In August 2013, in order to certify compliance with Title III of the Energy Conservation and Production Act (ECPA), the Governor’s Office of Energy Policy estimated that the communities collectively containing almost two-thirds of Arizona’s 2010 population (65.4%) had adopted either the 2009 or the 2012 IECC, and another 14.7% had adopted the 2006 IECC. Read the state certification here.

Current Residential Code

No statewide code. ACEEE estimates that over 90% of Arizona’s population is covered by either the 2009 or 2006 IECC.
